Why does the old Teana 230jk consume so much fuel?

[MaximusAnn]

The old Teana 230jk consumes excessive fuel due to faulty oxygen sensors and excessive engine carbon deposits. Below are specific details about the Teana: 1. Background: The Teana is a flagship mid-to-high-end luxury sedan under NISSAN. With cutting-edge technology, it perfectly combines Driving Technology (Precision Driving Engineering) and Comfort Technology (Absolute Comfort Engineering), bringing the design concept of mid-size sedans to a new level. The exceptional qualities of this all-new NISSAN premium luxury sedan, introduced to the Chinese market through the Bluebird and Sunny models, and imported via Nissan's Taiwanese joint venture, position the Teana as the first true product of the collaboration between Dongfeng and Nissan. 2. Exterior Design: Nissan's chief designer, Nakajima, reportedly envisioned the Teana as a 'sculpture in motion.' The sharp angles of the headlights are exceptionally well-defined, and the arc of the integrated body bumper rises from the sides to the outer edges of the headlights. A sleek waistline naturally extends from the outermost edges of the headlights, running fluidly from front to rear, complemented by a rounded roofline that creates a dynamic and elegant silhouette.
